I'm betting on NEVER. 14,000-something will be the all-time high. Our grandchildren (if we ever survive long enough to have them) will learn know of this number and its significant association with the peak of capitalist American society. They won't learn of the aftermath soon after the DOW retreated from 14,000 but will be told none of it was pretty in the coming years.
I've lost count at how many yuppies around me have lost in their continual seeking of nearly fraudulent ROIs. Keep gambling, asswads. Stupid people deserve to suffer, and as for suffering in the coming Depression, you'll have plenty.
I have money since I save and don't gamble. The gamblers are ALWAYS fooled since they have money temporarily. Then the Great Averager shows up and takes it away ... cue BAWWWWWWing.
